Loss of a key protein leads to defects in skeletal development including reduced bone density and a shortening of the fingers and toes—a condition known as brachydactyly. The discovery was made by researchers at Penn State ...

A molecular signaling pathway identified by an international research team could be the basis of improved treatment for osteoporosis. In their report published in the online journal Nature Communications, the investigators ...

In an advance that helps clarify the role of a cluster of neurons in the brain, Yale School of Medicine researchers have found that these neurons not only control hunger and appetite, but also regulate bone mass.

In the bones supporting our bodies, calcium regulation occurs by balancing the activities of osteoclasts, which are groups of cells that increase the calcium concentration in blood by destroying bone tissue, and osteoblasts, ...

Everyone knows that as we grow older our bones become more fragile. Now a team of U.S. and German scientists led by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) ...

Researchers at Whitehead Institute have identified a protein that is the target of glucocorticoids, the drugs that are used to increase red blood cell production in patients with certain types of anemia, including those resulting ...

Bone density

Bone density (or bone mineral density) is a medical term referring to the amount of matter per cubic centimeter of bones. It is measured by a procedure called densitometry, often performed in the radiology or nuclear medicine departments of hospitals or clinics. The measurement is painless and non-invasive and involves minimal radiation exposure. Measurements are most commonly made over the lumbar spine and over the upper part of the hip. The forearm is scanned if either the hip or the lumbar spine can't be.
